	All the public networks the Ocean Protocol contracts are deployed to.

Networks

Ocean Protocol's smart contracts and OCEAN are deployed on multiple public networks: several production chains, and several testnets too.

address.json holds up-to-date deployment addresses for all Ocean contracts.

You need the network's native token to pay for gas to make transactions: ETH for Ethereum mainnet, MATIC for Polygon, etc; you typically get these from exchanges. You also need "fake" native tokens for testnets; you typically get these from faucets.

Networks Summary

Here are the networks that Ocean is deployed to.

Production Networks:

• Ethereum mainnet
• Polygon mainnet
• Oasis Sapphire mainnet
• BNB Smart Chain
• Energy Web Chain
• Optimism Mainnet
• Moonriver

Test Networks:

• Görli
• Sepolia
• Mumbai
• Oasis Sapphire testnet
• Optimism Sepolia

The rest of this doc gives details for each network. You can skip it until you need the reference information.

Production Networks

Ethereum Mainnet

The Ethereum mainnet is a production network, which means that it is a live and operational network that handles real transactions and has actual economic value. To connect to the Ethereum mainnet using a wallet such as MetaMask, you can click on the network name dropdown and select Ethereum mainnet from the list of available networks.

Polygon Mainnet

Ocean Protocol is also deployed to Polygon Mainnet, which is another production network. The native token of Polygon Mainnet is MATIC. If you cannot find Polygon Mainnet as a predefined network in your wallet, you can manually connect to it by following Polygon's guide, which provides step-by-step instructions for connecting to Polygon Mainnet.

Bridge

Check out the Polygon Bridge guide to learn how you can deposit, withdraw and send tokens.

Oasis Sapphire Mainnet

Ocean Protocol is also deployed to Oasis Sapphire Mainnet, which is a production network that Ocean Protocol uses for Predictoor. Ocean Protocol does do not currently support ocean.js, ocean.py, or Ocean Market on Oasis Sapphire. The native token of Oasis Sapphire is ROSE. If you cannot find Oasis Sapphire Mainnet as a predefined network in your wallet, you can manually connect to it by entering the following information during the import process: Network Name: Oasis Sapphire, RPC URL: https://sapphire.oasis.io, Chain ID: 23294, Token: ROSE.

Test Networks

Görli

Ocean Protocol is deployed on the Görli test network, which is used for testing and experimentation. Tokens on Görli do not hold real economic value, as it is a non-production network. To connect to Görli using a wallet like MetaMask, simply click on the network name dropdown and select Goerli from the list of available networks.
